Process leading to supernova explosions and cosmic radio bursts unearthed at PPPL

A promising method for producing and observing on Earth a process important to black holes, supernova explosions and other extreme cosmic events has been proposed by scientists at Princeton University's Department of Astrophysical Sciences, SLAC National Acceleraor Laboratory, and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The process, called quantum...

Improving the evidence: Scientists review quantitative climate migration literature

Quantitative empirical studies exploring how climatic and other environmental drivers influence migration are increasing year by year. PIK scientists have now reviewed methodological approaches used in the quantitative climate migration literature. Their review plays an important role when it comes to assessing how climatic factors influence human migration, and provides guidance to researchers...

How the expanded child tax credit is helping families

American households making less than $50,000 are more likely than higher-earning families to spend the expanded child tax credit on essential expenses and tutors for their children, found a survey from the Social Policy Institute (SPI) at Washington University in St. Louis.

Physicists report promising approach to harnessing exotic electronic behavior

For some 50 years scientists have worked to harness Bloch oscillations, an exotic kind of behavior by electrons that could introduce a new field of physics—and important new technologies—much like more conventional electronic behavior has led to everything from smart watches to computers powerful enough to get us to the Moon.

Waterhemp goes off script to resist herbicides

Cementing waterhemp's reputation as a hard-to-kill weed in corn and soybean production systems, University of Illinois researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.

New way to image whole organisms in 3D brings key skin color pigment into focus

To understand the biological underpinnings of skin and hair pigmentation and related diseases such as albinism or melanoma, scientists and doctors need quantitative, three-dimensional information about the architecture, content and location of pigment cells. Penn State College of Medicine researchers have developed a new technique that allows scientists to visualize every cell containing melanin...

This hydrogel tablet can purify a liter of river water in an hour

As much as a third of the world's population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.

An X-ray view of carbon

At the heart of planets, extreme states are to be found: temperatures of thousands of degrees, pressures a million times greater than atmospheric pressure. They can therefore only be explored directly to a limited extent—which is why the expert community is trying to use sophisticated experiments to recreate equivalent extreme conditions. An international research team including the...

A new way to remove troublesome ions from water

Converting seawater into fresh water is important in water-scarce countries. For that process, certain charged particles—known as ions—have to be removed from the water. However, some ions are difficult to remove from water due to their chemical properties. Recent research by scientists from Israel and the Netherlands is helping to improve this ion-removal process.

Molecular scales on biological membranes

Cellular processes on membranes are often fast and short-lived. Molecules assemble briefly, separate again, interact with different partners and move along or through the membrane. It is therefore important to not only study static snapshots of these processes, but also to understand their dynamics. But how can this be achieved methodically? Petra Schwille from the Max Planck Institute of...

Researcher analyzes 99 gay/trans panic defense cases

St. Edward's University Associate Professor of Criminal Justice Carsten Andresen is shedding light on a controversial legal strategy, called the gay/trans panic defense, in what is believed to be the largest analysis of gay/trans panic defense murder cases in the social sciences so far.

Research gives new insight into capitalizing on momentum investing

Every investor is chasing the answer to one question: When should I buy stocks and when should I sell them? It's the elusive formula for timing the market. New research co-authored by Albert "Pete" Kyle, the Charles E. Smith Chair Professor of Finance at the University of Maryland's Robert H. Smith School of Business, shows how markets gain momentum and how investors can make better decisions...

Discovery of new marine worm species

Researchers from the Swedish Museum of Natural History have identified a new species of marine worm living in the Basque region of Spain. Named Faerlea assembli, the worm is just 0.8mm long and was discovered as part of research conducted at Plentzia Marine Station.
